Application filed November To all whom it may concern: Be it known that I, Virus Sonwnumonu a subject of the German Emperor, and residing at Oggersl'ieim, near l lannheim, Germany, have invented certain new and useful mprovements in Apparatus for liaising Liquids, of which the following: is a specificetioli. The present invention relates to apparzdus for raising liquids and an important object is ,to provide improved apparatus for elevating liquids by n1eans of steam or other gaseous fluid under pressure admitted by means of an electrically controlled admission valve.

In t 1e present invention the electric.' ir by means of which the valve-controlling electr'omagnet or solenoid is energized for opening the valve is closed by the arrival of the level of the liquid at an upper contact, remains closed until the level of the liquid has fallen through a predetermined di tance Oil-e construction embodying the invention is shown b r Way of example in the accompanying drawing, in whichigure 1 is a vertical elevation. or" the appa ratus, partly in section, and Fig. 2 is a like view of a detail on' alarger scale.

eferring to thedrayving, 1 is the rcssure chamber, and Zthedelivery pi e. Tile latter is electrically conductive anv extends into the chamber, as clearly shown, ally insulated from the Walls of the chamer. The valve 3 enables the delivery pipe to be placed in communication with the supply pipe 4.

5 is the inlet pipe for the fluid under pressure; this pipe can be'placed m eonumuucae pressure pipe 6 by means oi the valve 7.

8 is the discharge valve for the expanded fluid, and whcn open enables the latter to piss through the orifice 9 into the atmosp 7 with the pivoted at against its seat. The spring 14, which is com aratively Weak, and abuts against the co lar 12 on the rod 13 of the valve 8, tends to hold thelatter open.

The up er contact hereinbefore referredto (F15, and is connected by the Wire l fi' wrth the electromagnet 17, the wire 16 be ing 'insulatedfrom the pipe 5 at 34. The electromagnet' l7 isconnected by the wire 33 with the battery or other source of current Specification of Letters Patent.

The union .222, in which the upper end of the wire 1-3] is: slidahlo, is connected to the contact-stud 23, as clearly shown in Fig. 2, and this stud is carried by but ii'isulatee from the lever 25 which is pi\' dted at 26.
